The larval head differs from that of E. longicnrnis Walker 

 or E. spinosa 0. S., as described before, in the following 

 essentials : 



Genal plates (plate I, D) at their inner cephalic anj^le evenly 

 rounded, not produced into a prominent lobe. The lahrum 

 (plate I, B) is much more produced, conical, bearing a little 

 tuft of hairs at the tip and a small, cylindrical, chitinized 

 tubercle on either side of the tip ; the lateral lobes are very 

 prominent, cylindrical, densely clothed with long short hairs, 

 the lobes bent prominently inward. Antennce (plate I, C, a) 

 more club-shaped, the distal end being larger than the base; 

 hairs at the apex short. Mandibles (plate I, G) with a promi- 

 nent conical tooth at mid-length, this tooth squarely truncated 

 at apex and bearing a smaller tooth at its side. Size of the 

 head-capsule, 2.7 by 1.2 mm., across the genal plates. 



Stigmal field (plate I, J) with the spiracles rounded-oval to 

 rounded, placed obliquely, very widely separated from one 

 another. Four conspicuous lobes surrounding the stigrmal field, 

 of which one pair are lateral and the other ventral. Each 

 lateral lobe slender, with a narrow straight black mark on its 

 inner face, at its inner end, this mark scarcely if at all enlarged; 

 the lobe bears a dense fringe of Ions', delicate, pale brown hairs 

 along its dorsal face, these hairs quite inconspicuous due to their 

 pale color. Each ventral lobe verv long and slender, the inner 

 face with a narrow, straight black line which is expanded out 

 at the base into a dark brown triangular mark which meets its 

 fellow of the opposite side on the median line, the two enclosing 

 a pale, oval area between them ; a fringe of rather long pale 

 hairs on the apical third of this lobe. A pale brown mark runs 

 from each stigma dorsad. Stigmal field almost destitute of 

 dark spots or marks. 



Described from several larva? taken in sandy banks of Fall 

 Creek, Ithaca, New York, May 30, 1913. 



PUPA, $ 



The male pupa is quite like the 9 described below; the 

 bristles on the lobes of the crest are very long, exceeding the
